  31. Pay Versus Performance Disclosure

    Pay Versus Performance Disclosure The following table sets forth information regarding the compensation actually paid to our CEO and our other Named Executive Officers compared to certain performance measures for the years ended December 31, 2023, 2022 and 2021. The disclosure included in this section is prescribed by SEC rules and does not necessarily align with how we or our Compensation Committee views the link between company performance and our Named Executive Officers’ pay. As a clinical-stage biotech company, our executive compensation program does not utilize the company’s financial results as the primary indicator to determine executive compensation. We believe that the creation of sustainable long-term stockholder value depends on our ability to successfully advance our HBV pipeline, and ultimately, bring those product candidates to market. Consequently, our Compensation Committee has designed our executive compensation program to incentivize our executive officers to create that value through the discovery and development of a robust and attractive pipeline of drug candidates. In determining the amount of the annual incentive award for each of our executive officers, including each of our Named Executive Officers but excluding Mr. Collier and Dr. Howard due to their respective terminations of employment in 2023, the Compensation Committee evaluated the corporate performance objectives that had been established at the beginning of the calendar year as well as other corporate and individual achievements and performance throughout the year. These performance objectives included clinical milestones for our lead product candidates, research and development milestones for our early-stage drug candidates and other business objectives. Additionally, grants of equity awards, primarily stock options and restricted stock units, to our executive officers are intended to incentivize future value creation and to align the long-term interests of our executive officers with shareholders. For further discussion of how the Company views its executive compensation structure, including alignment with Company performance, see page 35. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown. The “Compensation Actually Paid”, which is presented in the table below, is defined by the SEC and does not reflect amounts actually paid, earned or received by our Named Executive Officers. A significant portion of the “Compensation Actually Paid” amounts shown relate to changes in values of unvested equity awards over the course of the applicable reporting year. These unvested awards remain subject to significant risk from forfeiture conditions and possible future declines in value based on changes in our share price. The ultimate values actually realized by our Named Executive Officers from unvested equity awards, if any, cannot be determined until the awards fully vest and are exercised or settled, as the case may be.

  35. Pay Versus Performance Disclosure

    | (3) “Compensation Actually Paid” is defined by the SEC and is computed in accordance with SEC rules by subtracting the amounts in the “Stock Awards” and “Option Awards” column of the SCT for each year from the “Total” column of the SCT and then: (i) adding the fair value as of the end of the reported year of all awards granted during the reporting year that are outstanding and unvested as of the end of the reporting year; (ii) adding the amount equal to the change as of the end of the reporting year (from the end of the prior year) in fair value (whether positive or negative) of any awards granted in any prior year that are outstanding and unvested as of the end of the reporting year; (iii) adding, for awards that are granted and vest in the reporting year, the fair value as of the vesting date; (iv) adding the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value (whether positive or negative) of any awards granted in any prior year for which all applicable vesting conditions were satisfied at the end of or during the reporting year; (v) subtracting, for any awards granted in any prior year that are forfeited during the reporting year, the amount equal to the fair value at the end of the prior year; and (vi) adding the value of any dividends (or dividend equivalents) paid in the reporting year on unvested equity awards and the value of accrued dividends (or dividend equivalents) paid on performance awards that vested in the reporting year. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. |

  40. DIRECTOR COMPENSATION

    DIRECTOR COMPENSATION To align the interests of non-executive directors with the long-term interests of Shareholders, our Board has approved the non-executive directors’ participation in our equity compensation plans, as well as an annual cash retainer. Members of our management team receive no additional consideration for acting as directors. Accordingly, Mr. Collier did not receive any compensation for his service as a member of our Board during 2023. Mr. Collier’s compensation for service as an employee for 2023 is presented above in the “Executive Compensation – Summary Compensation Table” section of this Proxy Statement/Circular.

  49. Director Compensation

    Director Compensation The Board believes that the level of director compensation should generally be competitive with the level of compensation paid to directors of the Company’s peer companies and that a significant component of such compensation should be tied to the performance of the Company. Accordingly, a significant portion of director compensation should be in the form of stock options and equity. The Executive Compensation and Human Resources Committee shall periodically review the compensation of non-management directors. The Executive Compensation and Human Resources Committee is encouraged to seek advice from an independent compensation consultant. After such review, the Executive Compensation and Human Resources Committee will make recommendations to the full Board, and the full Board will determine the non-management director compensation. The Company’s employee directors shall not receive additional compensation for service as directors.
